Returns a select tag with options for each of the hours 0 through 23 with the current hour selected. The hour can also be substituted for a hour number. Override the field name using the :field_name option, ‘hour’ by default.

Examples

my_time = Time.now + 6.hours

# Generates a select field for minutes that defaults to the minutes for the time in my_time
select_minute(my_time)

# Generates a select field for minutes that defaults to the number given
select_minute(14)

# Generates a select field for minutes that defaults to the minutes for the time in my_time
# that is named 'stride' rather than 'second'
select_minute(my_time, :field_name => 'stride')
